"We cannot have in the Olympic programme a game which is promoting violence or discrimination," Bach said. "So-called killer games. They, from our point of view, are contradictory to the Olympic values and cannot therefore be accepted."

Bach was an Olympic-level fencer, for which he won a gold medal at the 1976 Summer Olympics.
